</div></div></div></blockquote><div><br>Ok, thanks.<br><br>So probably, I'd need this cone at one point if I'm playing with Klein. The problem is that's an Xcode project, and there is no makefile. I'll see that if I need it.<br>

<br>As far as I can think, the VM itself can't be written in a language that requires a VM. Or else, we'd need to maintain that VM itself. The only way is to get a compiler for Self.</div></div></div></div></div>
</div></blockquote></div><div>You underestimate the Self System a bit here, it was the one that developed the Java JIT Hotspot stuff, before it it became that.</div><div>Klein is basically a Self compiler, yes it is also a VM, but with JIT now supported by most other languages it's not so uncommon anymore ;)</div>
<div>What it does when bootstrapping the VM is basically emitting the JIT code and then deep freezing it by statical linking and exporting to a file.</div></div></div></div></div></blockquote><div><br>That's what I thought after I found the 2005 paper describing Klein.<br>
Apparently, there is a PPC assembly backend that works, i386 and sparc modules. Basically, what is needed is a llvm backend so it could be cross platform.<br><br>
